When warm ventilation pipe uses, the dust in middle tuber pipe 3 and the side air pipe 4 drops to in the drawer 51 of receiver 5 below, is adsorbed the collection back by moist cleaning paper 52 afterwards, realizes the stable collection of dust. When cleaning up the collected dust, the pressing lever 53 is rotated to disengage the drawer 51, and then the drawer 51 is pulled out. Then the cleaning paper 52 is directly taken out, and the dust is taken out by the cleaning paper 52, so that the dust can be cleaned.
After the dust is cleaned, after new cleaning paper 52 is laid in the drawer 51, the cleaning paper 52 is wetted, and then the drawer 51 is reinserted into the storage case 5. Finally, the pressing rod 53 is rotated to press the outer wall of the drawer 51, so that the drawer 51 is installed and fixed.
As shown in fig. 2 and 4, a dovetail-shaped side mounting block 21 is horizontally provided at the lower end of the side tie bar 2, a side mounting seat 41 is horizontally provided at the upper end surface of the side duct 4, a side groove 42 into which the side mounting block 21 is fitted, and a pair of side mounting grooves 43 communicating with both ends of the side groove 42 and into which the side mounting block 21 is slidably fitted are provided at the upper end surface of the side mounting seat 41.
As shown in fig. 3 and 4, a dovetail-shaped middle mounting block 11 is horizontally arranged at the lower end of the middle pull rod 1, a middle mounting seat 31 is horizontally arranged on the upper end surface of the middle air duct 3, a middle groove 32 for the middle mounting block 11 to be embedded in and a middle mounting groove 33 which is communicated with the side wall of the middle groove 32 and for the middle mounting block 11 to be slidably embedded in are arranged on the upper end surface of the middle mounting seat 31.
As shown in fig. 4, both ends of the intermediate air duct 3 are provided with intermediate flanges 6, both ends of the side air ducts 4 are provided with side flanges 7, a fixing portion 8 for mutual fixation is provided between two adjacent side flanges 7, and a locking portion 9 for mutual locking is provided between the intermediate flanges 6 and the side flanges 7.
When the heating ventilation pipe is installed, the side air pipe 4 is taken out firstly, and the side installation seat 41 on the side air pipe 4 faces upwards. Then the side air duct 4 is driven to move upwards, so that the side mounting block 21 at the lower end of the side pull rod 2 is embedded into the side groove 42 on the side mounting seat 41, and then the side air duct 4 is driven to be far away from the side pull rod 2. At this time, the side mounting block 21 gradually slides into the side mounting groove 43, thereby realizing the hoisting of the side air duct 4.
And after the side air pipes 4 are completely hoisted, the side flanges 7 at the end parts of the side air pipes 4 positioned at the two sides of the middle pull rod 1 are mutually butted. And then, the two adjacent side flanges 7 are fixed by the fixing parts 8, so that the installation and the fixation between the side flanges 7, namely the fixation of the plurality of side air ducts 4, are realized.
Meanwhile, a gap for installing the middle air duct 3 is left below the middle pull rod 1, and the length of the gap is the same as that of the middle air duct 3. The intermediate air duct 3 is then removed with the intermediate mounting seat 31 on the intermediate air duct 3 facing upwards.
Then the middle air duct 3 is driven to move upwards, so that the middle mounting block 11 at the lower end of the middle pull rod 1 is embedded into the middle groove 32 on the middle mounting seat 31 after the middle air duct 3 is positioned in the reserved gap. Then the middle air duct 3 is driven to horizontally slide, after the middle mounting block 11 is embedded into the middle mounting groove 33, the middle air duct 3 is completely aligned with the side air duct 4, and the middle flange 6 is abutted against the side flange 7. And finally, after the middle flange 6 and the side flanges 7 are fixed by the locking part 9, the whole heating ventilation pipe is installed and fixed.
As shown in fig. 4, a ring of sealing ring 71 is disposed on the side flange 7 of the side air duct 4 away from the intermediate air duct 3, a sealing groove 72 for embedding the sealing ring 71 is disposed on the other flange, and a rubber gasket 61 is disposed between the intermediate flange 6 and the side flange 7.
When the side air duct 4 is installed, the stepped sealing between the side flange 7 and the side flange 7 is realized by the matching of the sealing ring 71 and the sealing groove 72, and the sealing performance between the side air duct 4 and the side air duct 4 is increased. Simultaneously through setting up rubber packing ring 61, realize sealed between intermediate flange 6 and the side flange 7, the leakproofness between tuber pipe 3 and the side air pipe 4 in the middle of the increase to the leakproofness of whole warm ventilation pipe of increase.
As shown in fig. 3, the intermediate duct 3 includes a pair of tube bodies 34, a rubber tube 35 is provided between the pair of tube bodies 34, and both ends of the rubber tube 35 are fixed to the end portions of the tube bodies 34. And both ends of the intermediate mounting seat 31 are slidably connected to the upper end surfaces of the pair of pipe bodies 34.
When the middle air duct 3 and the side air duct 4 are produced, production errors are avoided, and when the middle air duct 3 and the side air duct 4 are installed, installation errors also exist. Therefore, the pair of tube bodies 34 and the rubber tube 35 are arranged to jointly form the intermediate air duct 3, so that the fine adjustment of the length of the intermediate air duct 3 is realized. Thereby effectual overcoming installation error and production error, avoiding appearing the dead or dislocation phenomenon of card, realize the quick installation and the easy to assemble of whole warm ventilation pipe.
As shown in fig. 2 and 4, the fixing portion 8 includes a plurality of horizontally disposed fixing rods 81, the fixing rods 81 are located on the side flanges 7 of the side air ducts 4 far away from the middle air duct 3, and the plurality of fixing rods 81 are distributed around the side flanges 7.
As shown in fig. 2 and 4, a screw 82 is connected to one end of the fixing rod 81 away from the side flange 7 in a threaded manner, and an elongated fixing block 83 is disposed at one end of the screw 82 away from the fixing rod 81.
As shown in fig. 2 and 4, a fixing hole 73 for the fixing block 83 to pass through is formed in the side flange 7 of the side duct 4 close to the intermediate duct 3, and the fixing block 83 passes through the fixing hole 73 and rotates to press the outer wall of the side flange 7.
When the side air duct 4 is installed, the fixing block 83 and the fixing rod 81 gradually penetrate through the fixing hole 73 until the pair of side flanges 7 are abutted against each other, and the fixing block 83 is completely separated from the fixing hole 73. At this time, the fixing block 83 is screwed, and then the fixing block 83 drives the screw rod 82 to rotate synchronously. After the fixed block 83 compresses tightly the outer wall of the side flange 7, the pair of side flanges 7 are compressed and fixed, and therefore the fixed portion 8 is locked and fixed.
As shown in fig. 3 and 6, a locking hole 62 communicating with the fixing hole 73 (see fig. 2) is formed through the intermediate flange 6, and the locking portion 9 includes a locking lever 91 inserted into the locking hole 62 and the fixing hole 73.
